Description

  The present invention relates to a liquid food bag used for directly feeding a liquid tube feeding agent to a gastrointestinal tract of a patient with an eating disorder such as a patient immediately after surgery or a bedridden patient to replenish nutrition.

  Gastrointestinal function is maintained but swallowing function, such as patients immediately after digestive surgery and brain surgery such as esophageal cancer removal, neuropathy such as sequelae of cerebral infarction and dementia, elderly patients who are bedridden Patients who are unable to eat orally due to disability should directly enjoy liquid foods such as enteral nutrients with good digestibility through a catheter inserted into the digestive tract such as the stomach or intestine from the nasal cavity, gastrostomy or jejunostomy The nutrition required for living body maintenance is replenished by administration.

  As a liquid food widely used, there is a semi-solid type having a viscosity of about 20,000 mPa · s. Such a semi-solid liquid food is enclosed in a bag or a bottle. Connect the bag to the catheter and pour liquid food into the gastrointestinal tract, suck up the liquid food from the bottle with a syringe, then connect it to the catheter and pour into the gastrointestinal tract, or a little longer than the healthy person's meal time For about 15 to 30 minutes. Semi-solid liquid foods can suppress backflow from the stomach due to its high viscosity, but liquid foods must be administered slowly, and medical staff such as nurses can handle liquid foods while handling bags little by little. It was administered by extruding and pouring, or by repeating the operation of pouring the liquid food from the bottle with a syringe and then pouring it over and over.

  Therefore, during the administration time, the medical staff must continue to administer the administration treatment, and it will be restrained only for the patient for a long time in the preparation treatment, administration treatment, and post-treatment after disposal. The amount of liquid food can be determined by tactile sensation, and the remaining amount of liquid food in the bottle can be visually determined. However, in the field of nursing and home medical care in a hospital, it is not only necessary for a single medical staff to administer a liquid meal of 2-3 meals every day. It is necessary to devote time for position change and rehabilitation nursing work, and lack of medical efficiency and completeness.

  Therefore, a catheter in which a low-viscosity liquid food that is in a liquid state with a viscosity of about 5 to 200 mPa · s until reaching the stomach, but changes to a semi-solid state by gastric acid when it reaches the stomach, is hung on a stand and suspended. In addition, the natural fall administration method in which the liquid food is transnasally administered to the digestive tract such as the gastrointestinal tract by gravity has been performed. This liquid food is easy to administer because it is a low-viscosity liquid before administration, and it becomes semi-solid in the stomach after administration and can prevent backflow from the stomach. In addition, this makes it possible to administer liquid food to a large number of patients with only one nurse, thereby improving efficiency and contributing to enhancement of nursing treatment.

  As such a liquid food bag, two substantially rectangular isomorphous films are aligned and the surrounding portions are bonded together by heat sealing to form a bag, and at a position on the substantially diagonal line of the rectangle, a suspension opening and Patent Document 1 discloses an infusion bag for dispensing a filled liquid content to a patient via an infusion tube.

  Moreover, as a bag for liquid foods, the bottom of the soft bag has a shape that can stand on its own and a hole for hanging, and has a spout on the upper diagonal of the hole, and a straight through hole on the diagonal Japanese Patent Application Laid-Open No. 2004-228688 discloses a liquid food soft bag provided with a scale.

JP 2002-95721 A Utility Model Registration No. 3072464

  Conventional liquid food bags are opaque or narrow even if they have straight through-holes. There was a problem that it was difficult to distinguish. Furthermore, since the conventional liquid food bag has straight through holes on the diagonal of the bag surface, it does not obstruct the display of the product etc., and the broken through hole is inconspicuous for the display of the product etc. There was a problem.

  To prevent the liquid food from remaining on the catheter after administration of the liquid food, the liquid food bag is opened and the cleaning water is poured or the cleaning water is injected from the inlet, and then the water is poured from the catheter into the gastrointestinal tract. Since a post-treatment is performed to prevent the propagation of germs by washing the inside, a through hole is provided along the side of the liquid food bag when it can be opened with a fastener or the like. In addition, there is a risk that water may be injected into the bag by mistakenly administering the medicine after diluting with water appropriately before administration while observing the through-hole. In this case, since the low-viscosity liquid food is diluted in advance, it loses its original function of being rapidly semi-solidified in the stomach.

  Therefore, there is a demand for a bag for liquid food that is easy to inject water after administration of liquid food, if necessary, while calling attention not to inject water into the bag before liquid food administration.

  The present invention has been made in order to solve the above-mentioned problems, and realizes that water must not be injected before administration of liquid food, or can be motivated not to inject water, so In addition to losing the function of semi-solidifying, the liquid food bag can be used to easily and reliably predict and discriminate the timing of completion of liquid food administration, and to ensure a sufficient product display area. For the purpose.

  The liquid food bag made to achieve the above-mentioned object can be connected to a flat and opaque pouch-like soft bag and a catheter that flows the liquid food enclosed in the soft bag into the digestive tract of a patient. A liquid food bag comprising a lower end side corner or an outflow port provided at a lower end side central part, wherein the upper end side of the soft bag is closer to one upper end side corner than the upper end side central part. A hanging suspension hole opened diagonally to the lower end side corner, and provided on at least one side of the soft bag, and along the diagonal direction, in the middle of the lower end side corner or lower end side center And a transparent endoscope window that is bent toward the part and can visually recognize the liquid level of the liquid food.

  In the liquid food bag, the endoscope window is 1/12 to 1/5 of the total amount of the liquid food enclosed, 30 to 70 mL of the remaining amount of the liquid food, and 5 of the completion of the outflow due to the natural fall of the liquid food It is preferable that the curve begins to bend toward the center of the lower end side, so as to indicate 10 minutes before and / or 1/2 to 1/4 of the lower side of the full length of the side side.

  In the liquid food bag, the endoscope window may be bent and / or curved toward the center of the lower end side.

  In the liquid food bag, the soft bag is formed by heat-sealing the periphery of a soft film-like soft bag sheet, and the outflow port is at the lower end side or the lower end side at the lower end side. It is more preferable that it is heat-fused at the center portion or between them.

  In the liquid food bag, for example, the soft bag sheet is a laminated film, and the outer layer of the inner layer or the intermediate layer covering the outer layer or the outer surface or the inner surface of the outer layer has a colored layer. The endoscope window is formed by not having a portion.

  In the liquid food bag, the hanging hole is opened at the upper end side corner, the outflow port is heat-sealed at the lower end side center, and the endoscope window is curved toward the lower end side corner. It may be what you are doing.

  In the liquid food bag, it is preferable that the endoscope window reaches the outflow port.

  In the liquid food bag, the endoscope window is more preferably white or black.

  In the liquid food bag, it is even more preferable that the endoscope window is bent with a width of 6 to 12 mm.

  In the liquid food bag, the total amount of the liquid food is 150 to 600 mL, and the length of the lower end side and the upper end side is 90 to 150 mm as the inner dimensions of the chamber for enclosing the liquid food in the soft bag. Those having a side length of 100 to 250 mm are preferred.

  In the liquid food bag, it is even more preferable that the endoscopic window bends toward the lower end side central portion in the middle of the other upper end side and near the corner of the other upper end side along the diagonal direction.

  The liquid food bag is a soft bag sheet on either side of the soft bag, in which a soft bag sheet tearing yarn is embedded from one corner of the other upper edge toward the one corner of the upper edge. Also good.

  The liquid food bag may be provided with a fastener that engages and holds the soft bag sheets on both sides of the soft bag near the lower end side along the soft bag sheet tearing yarn.

  The liquid food bag may be one in which a water inlet is provided in the soft bag.

  In the liquid food bag, it is even more preferable that the liquid food is a liquid having a viscosity of 5 to 200 mPa · s and changes into a semi-solid state by stomach acid in the stomach.

  The liquid food bag may have a scale and / or a remaining amount value attached to the endoscopic window that are aligned along the horizontal direction when the liquid food bag is hung from the hanging hole.

  The liquid food bag of the present invention can be administered to the digestive tract of the stomach or the like, especially from the patient's nasal cavity or gastrostomy / jejunostomy, particularly from the nasal cavity, via the nasal cavity, by the spontaneous fall administration method. it can.

  According to this liquid food bag, when the endoscopic window is along the diagonal line from the upper end side corner to the lower end side corner, it is in an upright direction and misappropriates before liquid food administration to inject water. It can be noticed that water should not be poured because the viewing window, its scale and remaining capacity values look diagonal. Since it is naturally alerted in this way, there is no risk of injecting water by mistake, and there is no fear of causing inhibition of semi-solidification of the liquid food in the stomach due to erroneous injection. Therefore, if the liquid food is liquid before administration and changes to a semi-solid state in the stomach after administration due to the stomach environment such as gastric acid, it does not flow back from the stomach.

  According to this liquid food bag, since the inside of the catheter is washed after liquid food administration to suppress the proliferation of germs as necessary, water can be simply injected into the bag, and then the residual flow in the catheter can be injected with the water. The food can be poured into the gastrointestinal tract.

  Also, according to this liquid food bag, the remaining amount of liquid food in the bag can be easily recognized visually by the endoscope window provided on the soft bag surface of the liquid food bag at the time of administration, It is possible to easily predict when the administration of a meal is completed, or to reliably determine the completion of administration.

  According to this liquid food bag, since the endoscopic window is substantially J-shaped, the liquid level of the liquid food can be seen in a wider area, especially as the administration is completed, so the timing of completion of liquid food administration can be predicted. It is easy to distinguish. In the middle of the administration from the start of administration, which is not necessary to be aware of the time when the administration is completed, the longitudinal portion of the endoscope window along the diagonal line from the upper end corner to the lower end corner at the center of the soft bag. At the end of the administration, when the necessity of continuation of administration is confirmed by visually checking the height of the liquid food liquid surface of the soft bag, it is directed to one corner of the lower end of the soft bag or the center of the lower end. Visually check the height and visible width of the liquid food liquid surface at the approximately J-shaped curved / bent areas and confirm that the administration is close to completion. It can be confirmed that almost no liquid food remains to be administered by visually confirming that the surface is no longer visible.

  According to this liquid food bag, when administering liquid food such as liquid enteral nutrient directly connected to a nasal catheter, gastrostomy catheter, or jejunostomy catheter, a nutrition set with a drip tube that can grasp the drip situation Even if you do not bother to use it, you can easily understand the dropping state of the liquid food. In particular, when a liquid food that is semi-solidified by acid in the stomach at 5 to 200 mPa · s before reaching the stomach is to be administered by natural fall, there is no infusion tube in the administration route, so that in the administration route such as a catheter. Even if it is difficult to visually recognize the flow status of the liquid food, there is a merit because it can be grasped by glimpsing the liquid food bag.

  According to this liquid food bag, since it can be administered surely and easily even in the nursing and home medical care settings in the hospital, it can be distributed to the patient's position and rehabilitation, etc. Contribute to improving the efficiency and fulfillment of nursing work.

  In this liquid food bag, the endoscopic window is located closer to one corner of the upper edge than the diagonal of the soft bag, so important names such as manufacturer name, product name, catalog number, ingredient, dose, volume, and calorie are important. A large number of items can be clearly displayed on the soft bag so that they can be easily seen near the lower end corner on the diagonal side of the upper end side of the soft window. At the same time, a considerable amount can be displayed closer to the corner of the upper edge than the endoscope window.

  In this liquid food bag, since the soft bag surface is colored except for the endoscope window, the liquid food enclosed is prevented from being deteriorated by active energy rays such as ultraviolet rays.

  Since this liquid food bag has a simple structure, it can be easily manufactured and can be used for a variety of products according to dose, calories, and component composition.

  Hereinafter, although the form for implementing this invention is demonstrated in detail, the scope of the present invention is not limited to these forms.

  One aspect of the liquid food bag 1 of the present invention will be described with reference to FIG. 1 which is a front view.

  As shown in FIG. 1, the liquid food bag 1 is heat-sealed at the periphery of a soft bag sheet made of a flexible thermoplastic resin, and the front side and the back side are substantially rectangular and are formed into a bag shape. Soft bag 10, liquid food 40 sealed in soft bag 10 and sterilized, and having a viscosity of about 5 to 200 mPa · s and changing to a semi-solid by contacting with acid in the stomach, and liquid food An outflow port 51 that can be connected to a catheter 54 (see FIGS. 6 and 7) that flows out into the gastrointestinal tract of the patient and is heat-sealed so that the liquid food 40 can be discharged at the lower end side corner portion 14a of the soft bag 10. I have. The soft bag 10 is inflated when the liquid food 40 is enclosed, and the outer shape is flat.

The liquid food bag 1 is substantially rectangular, and a corner is notched at one lower end side corner portion 14 a of the lower end side 14. On that side edges 11 of the bottom side corner cutout corner portions 14a ₁ and the intermediate of the lower end side corner cutout central portion 14a ₂ of the lower end side corner cutout corner portions 14a ₃ of the lower edge 14 side, the outlet port 51 is heat sealed ing.

  The liquid food bag 1 is formed into a bag shape by heat-sealing two soft film-like soft bag sheets constituting the soft bag 10 at the entire periphery.

  The soft bag 10 is widely heat-sealed in the vicinity of the upper end side corners 12a and 12c on the upper end side 12 side, which is the upper end when suspended from the entire periphery. The soft bag 10 is heat-sealed with a uniform width except for the vicinity of the upper end side corners 12a and 12c among the entire periphery.

  The soft bag 10 has a hanging suspension hole 30 penetrating from the lower end side corner portion 14a diagonally to the upper end side 12 and closer to the upper end side one corner portion 12a than the upper end side central portion 12b. ing.

  The soft bag 10 is sandwiched between a laminated soft bag sheet on the front side and a laminated soft bag sheet on the back side at the lower end side corner portion 14a, and the outflow port 51 is heat-sealed. The outflow port 51 has an outflow hole 51 a (see FIG. 4) leading to the inside and outside of the soft bag 10.

  The soft bag 10 encloses the liquid food 40 while being isolated from the outside by heat sealing the periphery and screwing the cap 52 into the outflow port 51.

  The soft bag 10 has an inner layer 10a made of a transparent polypropylene (CPP) layer having a thickness of 70 μm, an intermediate layer 10b made of a biaxially stretched (ONY) 15 μm transparent polyamide (PA) layer, and an outer layer 10c made of 12 μm of transparent polyethylene. A terephthalate (PET) layer is formed by a laminated film-like soft bag sheet. A printed colored layer 10d is provided on the outer surface of the outer layer 10c. A soft bag 10 is formed by a film-like plastic sheet made up of an inner layer 10a, an intermediate layer 10b, an outer layer 10c, and a colored layer 10d, and almost the entire surface is shielded from light and becomes opaque (see FIG. 2).

The soft bag 10 has a transparent endoscope window 20 through which the liquid surface 41 of the liquid food 40 can be visually recognized by not having a part of the colored layer 10d on the front side which is one side thereof. Endoscopic window 20 from the upper side central portion 12b near the soft bag 10, along the diagonal D of the lower end side corner cutout central portion 14a ₂ of the upper side corner portion 12a near the risked hanging hole 30 and the lower side corner portion 14a Thus, the vertically long portion 22 is formed by extending straight up to the middle of the lower end side 14 side. Endoscopic window 20 is gently curved from there up to the outlet hole 51a near the lower end edge 14 of the lower end side corner cutout central portion 14a ₂ or lower side central portion toward 14b outlet port 51, the curved portion 23 Is forming.

  When the liquid food bag 1 is hung from the hanging hole 30 and flows out of the liquid food 40, it can be visually observed through the endoscope window 20 that the liquid level is lowered according to the outflow. .

  In the endoscope window 20, the boundary from the vertically long portion 22 to the curved portion 23 is 1/12 to 1/5, preferably 1/10 to 1/5 of the total amount of the liquid food 40, or the remaining amount of the liquid food 40. 30 to 70 mL, or 5 to 10 minutes before completion of outflow due to natural fall of the liquid food 40, preferably 5 to 7 minutes before, or 1/2 to 1/4 of the lower side of the total length of the side 13, preferably 1 When the position is in the range of ３〜 to ¼, it becomes easy to predict and confirm the administration completion timing.

  In the liquid food bag 1, for example, the total amount of the liquid food 40 is 150 to 600 mL, preferably 200 to 550 mL. The lengths of the lower end side 14 and the upper end side 12 are the inner dimensions of the non-heat-sealed chamber that encloses the liquid food in the soft back so that the liquid surface 41 of the liquid food 40 can be easily seen from the endoscope window 20. It is 90 to 150 mm, preferably 105 to 125 mm, and the length of the sides 11 and 13 is 100 to 250 mm, preferably 150 to 205 mm.

  Immediately after the start of administration, the liquid level 41 of the liquid food 40 is visually observed from the longitudinally long portion 22 of the endoscope window 20 in the middle of administration, and the liquid level 41 at the curved portion 23 of the endoscope window 20 from the end of administration to the completion of administration. The necessity of continuation of administration and the completion of administration can be confirmed by visually observing.

  The width of the endoscope window 20 is equally 6 to 12 mm, preferably 6 to 10 mm, in the vertically long portion 22 and the curved portion 23. If this width is too thick, the light shielding property of the soft bag 10 may be reduced, and the liquid food 40 may be deteriorated by light. On the other hand, if this width is too thin, the liquid surface 41 of the liquid food 40 will be difficult to see.

The endoscope window 20 is provided with a scale and / or a remaining amount value that follows the horizontal direction when the liquid food bag 1 is suspended and suspended in the hanging hole 30. Vertical portion 22 of the endoscope window 20, by which along a diagonal D of the upper side corner portion 12a and the lower end side corner cutout central portion 14a _2, and the upright direction trying inject water before liquid diet administration The vertical portion 22 of the endoscopic window 20, the scale of the endoscopic window 20, and the remaining amount appear obliquely and feel uncomfortable, so that it is naturally alerted that water cannot be injected.

  The edge 21 of the endoscope window 20 is edged in white or black. Due to this edge 21, a difference in color tone between the liquid food 40 that is milky white or light yellow and the colored layer 10d that is a conspicuous chromatic color such as yellow, pink, red, and green (see FIG. 2) stands out, and the color tone of the colored layer 10d The liquid level 41 of the liquid food 40 can be confirmed more clearly without being affected by the above. The edge 21 is printed by printing in the same manner as the colored layer 10d.

  Since the important description items 15a and 15b such as manufacturer name, product name, catalog number, ingredient, dose, volume, heat amount, and usage precautions are printed on the colored layer 10d, the liquid food bag 1 At first glance, it can be distinguished from other products. Further, since the endoscope window 20 does not obstruct the print area of the description item 15 as much as possible, the description items 15a and 15b can be clearly displayed on the soft bag 10 so as to be easily understood.

  Since the endoscope window 20 is provided closer to one upper end side corner 12c than the diagonal D (upper right side of the soft bag 10 in FIG. 1), closer to one lower end side corner 14a than the diagonal D ( In the same figure, it is possible to clearly and sufficiently display the description items 15b of fine characters such as usage precautions and components on the lower left side of the soft bag 10). Further, near the upper edge side corner 12c of the diagonal line D, a large-character description item 15a such as a contravenous injection, a nasal nutrient, a product name, a dose, a volume, and a calorie can be clearly displayed.

  The soft bag sheet tearing yarn 33 is buried in the soft bag sheet on either side of the soft bag 10 from the other upper end side piece corner 12c toward the upper end side piece corner 12a. One end of the soft bag sheet tearing yarn 33 is connected to the knob 32 on the upper end side corner 12c side.

  A pair of fasteners 34 that engage and fasten the soft bag sheets on both sides of the soft bag 10 near the lower end side 14 along the soft bag sheet tearing thread 33 are attached to the inner surface side of each soft bag sheet. . The fastener 34 is a plastic fastener formed by engaging a long groove fastener 34a and a protruding fastener 34b (see FIG. 4).

  After the liquid food is administered, the liquid food bag 1 is opened with the soft bag sheet tearing yarn 33, and a small amount of washing water 42 (see FIG. 6) of about 30 to 50 mL is poured therein, and the water is poured into the catheter as it is. Therefore, it is convenient to clean the inside of the catheter so that no liquid food remains on the catheter and to suppress the propagation of germs. With this amount of washing water 42, since the already administered liquid food has been gelled, it does not flow back through the gastrointestinal tract.

  Although the example in which the endoscopic window 20 is provided only on one side of the front side of the soft bag 10 is shown, it may be provided symmetrically on both the front side and the back side of the soft bag 10. If both sides are provided, the endoscopic window 20 can be confirmed at a glance without considering the orientation of the liquid food bag 1 from both the front and back directions, which contributes to simplifying the confirmation work of the medical staff.

  It is even more preferable that the endoscope window 20 reaches the outflow hole 51a of the outflow port 51 in the lower end side central portion 14a. Thereby, since the position of the outflow hole 51a of the outflow port 51 and the end position of the endoscopic window 20 coincide, the liquid food 40 can be reliably maintained until administration is completed while being easily visible.

  The liquid food 40 is an enteral nutrient having a viscosity of 5 to 200 mPa · s, preferably 8 to 180 mPa · s, more preferably 10 to 150 mPa · s before reaching the stomach. It is good to semi-solidify with the acid inside.

  The liquid food 40 includes, for example, a nitrogen source, a powdered nutritional food containing lipids, and a gelling agent such as pectin that is gelled with stomach acid, and if necessary, contains carbohydrates, vitamins, and minerals. To do.

  The nitrogen source that is a protein source is not particularly limited as long as it can be used in foods. For example, milk protein such as whey and casein, egg white, gelatin, collagen, soy protein, and partial hydrolysates thereof. A decomposition product is mentioned. Examples of the lipid include rice oil, coconut oil, soybean oil, corn oil, and mixtures thereof. Examples of the gelling agent include pectin that is gelled at a pH of 3 or less, and more specifically, pectin having an esterification degree (DE value) indicating the content of methoxyl group of 40% or less.

As shown in FIG. 3A by omitting the items 15a and 15b, the heat-sealed portion of the liquid food bag 1 includes a curved portion 23 and a lower-end side corner cut-out corner portion 14a ₁ of the lower-end side corner portion 14a. When the lower end and verge thermal fusion site and unfused portions at sides corner cutout corner portions 14a ₃ and up side edge 11 is curved substantially parallel, complete flow out close to the outflow complete liquid diet 40 This is preferable because the visibility of the outflow situation until the time becomes even smoother.

  As shown in FIG. 2B, the liquid food bag 1 is provided with a hanging hole 30 that is hung on an extended portion protruding in a tongue shape, closer to the upper end side corner portion 12a than the upper end side center portion 12b. It may be. The upper end side 12 is heat-sealed substantially straight, and the hanging suspension hole 30 is provided so as to protrude beyond the upper end side 12, so that the accommodation capacity of the liquid food 40 of the soft bag 10 can be further reduced. . Further, the cleaning water inlet 35 may be provided by being heat-sealed to the upper end side 12, for example, the upper end side central portion 12b.

  As for the liquid food bag 1, as shown in the figure (c), the soft bag 10 itself may be a rectangle. Moreover, the outflow port 51 may be provided in the lower end side center part 14b. Thereby, since a shape becomes simple and a manufacturing process can be simplified, preparation of the liquid food bag 1 becomes still easier.

Liquid food bags 1, as shown in FIG. 2 (d), the endoscopic windows 20, bent to the outlet holes 51a near the outlet port 51 toward the longitudinal portion 22 to the lower end side corner cutout central portion 14a _2, A bent portion 23 'may be formed. As a result, the liquid level 41 of the liquid food 40 suddenly appears wide at the end of administration, and the liquid level 41 that was widely visible at the completion of administration disappears suddenly.

In the liquid food bag 1, as shown in FIG. 5E, the inner window 20 bends inward to the vicinity of the outflow hole 51 a of the outflow port 51 from the vertically long portion 22 toward the lower end side corner cutout central portion 14 a ₂ . However, the outer side may be curved to form a bent / curved portion 23 ″. This allows the liquid surface 41 of the liquid food 40 to suddenly become more widespread at the end of administration, and at the completion of administration. Since it becomes clearer how the liquid level 41 that has been widely seen disappears gradually, it is easy to grasp the completion of the administration of the liquid food 40.

  As shown in FIG. 5F, the liquid food bag 1 has a plurality of curved portions 23a, 23b, and 23c, so that the liquid surface 41 of the liquid food 40 has a plurality of curved portions 23a. The remaining amount of the liquid food 40 can be predicted in more detail depending on which of 23b and 23c is visible. Of the plurality of curved portions, the curved portions 23a and 23b that are not continuous with the vertically long portion 22 are provided so as not to interfere with the printing region.

  The soft bag 10, the outflow port 51, and the cap 52 of the liquid food bag 1 are made of thermoplastics other than those described above, such as polyethylene, polypropylene, polybutene, polybutadiene, polyisoprene, poly-4-methylpentene-1, polystyrene, At least one of the group consisting of polyvinyl acetate, polymethyl methacrylate, polyethyl methacrylate, polyacrylic acid, cyclic polyolefin, polyacrylonitrile, polyamide (nylon), polyester, polyurethane, polycarbonate, polyimide, polyphenylene sulfide, and polyvinyl chloride Homopolymers and / or copolymers and / or polymer blends may be included. When the soft bag 10 of the liquid food bag 1 is a laminated soft bag sheet made of a multilayer film, the film-like intermediate layer 10b may be an aluminum foil having an open viewing window 20.

  The liquid food bag 1 as shown in FIG. 1 is manufactured as shown in FIG. First, the outflow port 51 and the cap 52 are formed by injection molding or the like with a thermoplastic plastic.

  Next, the plastic bag 10 is formed by heat-sealing two laminated soft bag sheets for forming a liquid food bag as follows.

  Important description items 15 such as manufacturer name, product name, catalog number, ingredient, dose, volume, heat quantity, etc. on the exposed surface of each plastic sheet on the front side and the back side of the outer layer 10c of the laminated soft bag sheet of the plastic bag 10. (Omitted in FIG. 4) and a colored layer 10d composed of a chromatic background color is printed with ink, and the edge 21 of the endoscope window 20 is printed with a plastic sheet on the front side, and the inside of the edge 21 is not printed. Thus, the endoscope window 20 is formed. Next, a plastic sheet forming the intermediate layer 10b is separately formed into a film and prepared. Next, a long groove fastener 34a is formed on the inner surface side of the plastic sheet forming the inner layer 10a of the soft bag sheet on the front side while forming the film. On the other hand, a plastic sheet constituting the inner layer 10a of the soft bag sheet on the back side is formed into a film shape, and a protruding fastener 34b that engages with the long groove fastener 34a is formed on the inner surface side.

  Next, in order to form the laminated soft bag sheets on the front side and the back side, the outer layer 10c, the intermediate layer 10b, and the plastic sheet as the inner layer 10a are bonded together and laminated. At that time, when forming the laminated soft bag sheet on the front side, between the outer layer 10c and the inner layer 10a, the upper end side is closer to the upper end side 12 than the groove fastener 34a, toward the upper end side single corner 12a, and the other upper end side. Lamination is performed so that the soft bag sheet tearing yarn 33 is filled from one corner 12c.

  The long groove fastener 34a of the inner layer 10a of the laminated soft bag sheet on the front side and the protruding fastener 34b of the inner layer 10a of the laminated soft bag sheet on the back side are engaged with each other.

  Heating the side edges 11 and 13 (see FIG. 1) from the both corners 12a and 12c on the upper edge 12 side to the corners 14a and 14c on the lower edge 14 side of the laminated soft bag sheet for forming a liquid food bag. Heat fusion is performed by a heat fusion method such as The upper end side 12 is heat-sealed to the inner side to such an extent that a hole can be formed at both the corner portions 12a and 12c. Each of the laminating soft bag sheets on the front side and the back side has a rectangular shape corresponding to the capacity of the liquid food 40 and is cut out at the corner of the lower end side corner portion 14a (see FIG. 1). When cut into a predetermined size, the bag-like soft bag 10 is opened at the lower end side 14 side.

  A hanging hole 30 is opened through a hole punching hole at one upper end side corner 12a on the upper end side 12 side of the opened bag-like soft bag 10. The cut 31 is made so that one end on the upper end side corner 12c side of the soft bag sheet tearing thread 33 is connected to the knob 32 at the other upper end side corner 12a.

Each pedestal 51b of the lower end side corner cutout corner portions 14a ₁ and a lower edge 14 of the lower side corner cutout corner portion 14a ₃ and the intermediate lower side corner cutout central portion 14a ₂ outlet port 51 which is sealed by a cap 52, the heat Seal by fusing. Finally, the liquid food 40 (see FIG. 1) is poured into the bag-like inner space from the opening, and the lower end side 14 is heat-sealed to produce the liquid food bag 1. The liquid food bag 1 is sterilized by high-pressure steam sterilization as necessary.

  The liquid food bag 1 is used as shown in FIG. The cap 52 of the liquid food bag 1 is opened, and the outflow port 51 is screwed into the bag-side connector 53 of the nasal catheter 54 so that it does not fall out at the outflow port step 51c. Next, the hanging hole 30 is passed through the hook 71 of the stand 70 to hang the liquid food bag 1. The liquid food bag 1 is slightly inclined due to its own weight. If necessary, the flow path of the liquid food 40 is adjusted by tightening the flow path of the catheter 54 with the clamp 55 (see FIG. 7). Then, the liquid food 40 slowly flows out from the liquid food bag 1 to the catheter 54 and is administered to the stomach of the patient 60. The liquid food gels in the stomach and does not reflux.

  Immediately after the start of administration, the liquid level 41 a of the liquid food 40 in the liquid food bag 1 is visible from the vertically long portion 22 of the endoscope window 20. Since the vertically long portion 22 of the endoscopic window 20 is elongated, the liquid surface 41a is not so different from the width of the vertically long portion 22, but the necessity of continuing administration by visually checking the height of the liquid surface 41a of the liquid food 40 Can be confirmed. Furthermore, since the whole liquid food bag 1 is swollen by the liquid food 40, the necessity of continuation of administration can also be confirmed by bending the upper end side 12 between the front side and the back side.

  In the middle of administration, it can be seen that the liquid level 41 b of the liquid food 40 gradually decreases from the vertically long portion 22 of the endoscope window 20 in accordance with the fact that the liquid food 40 has flowed out somewhat. Furthermore, the necessity of continuation of administration can also be confirmed by the fact that the upper end side 12 is bent while the whole of the liquid food bag 1 is swollen by the liquid food 40.

  At the end of administration, the liquid food bag 1 is considerably deflated by the liquid food 40 and the upper end side 12 is stretched without bending, but it is difficult to identify the remaining amount only by the deflation. In addition, when the remaining liquid amount of the liquid food 40 decreases and the liquid level 41 decreases, the differential pressure cannot be obtained, and the liquid food 40 hardly flows out. Nevertheless, since the liquid food bag 1 is inclined by its own weight when suspended, the liquid level 41c of the liquid food 40 is changed to the endoscope window according to the fact that the liquid food 40 has flowed out considerably. From the 20 curved portions 23, the liquid surface 41c appears to gradually widen while gradually decreasing, so the visibility is improved and it can be clearly confirmed that the administration is almost complete.

  Thereafter, at the time when the administration is completed, it can be clearly confirmed visually that the administration has been substantially completed by the liquid level becoming invisible from the endoscope window. Furthermore, when the liquid food 40 falls down naturally, the liquid food bag 1 becomes negative pressure. At that time, the inner surface of the front-side soft bag sheet at the endoscope window 20 and the inner surface of the back-side soft bag sheet are in close contact with each other. By visually confirming that the liquid level 41 of the liquid food 40 can be visually recognized, it can be clearly confirmed that the liquid food 40 to be administered does not remain, that is, the administration is completed.

  When the administration of the liquid food is completed, the liquid food bag 1 is removed from the patient side connector 56 of the nasal catheter 54, and the liquid food bag 1 is discarded. On the other hand, the connecting part of the nasal catheter is washed with white hot water, washed with vinegar or disinfectant as needed, and the connector of the nasal catheter is closed with a cap.

  It is preferable to prevent the propagation of germs on the nasal catheter by preventing the liquid food from remaining in the nasal catheter as much as possible. Therefore, when administration of the liquid food is completed, as shown in FIG. 6, the tab 32 is picked up and pulled to the front side to tear the front side soft bag sheet and open the groove fastener 34a and the protruding fastener 34b. Open the mesh, inject white hot water from there, and re-engage the groove fastener 34a and protruding fastener 34b as necessary to prevent germs and dust from the outside from entering the liquid food bag 1. The inside of the catheter may be washed by pouring into the catheter. When the cleaning of the catheter is completed, the liquid food bag 1 is removed from the patient side connector 56 of the nasal catheter 54, and the liquid food bag 1 is discarded. Wash the site of the nasal catheter with white hot water, wash with vinegar or disinfectant if necessary, and close the connector of the nasal catheter with a cap.

  If the liquid food bag 1 is used, it takes about 60 minutes from preparation to disposal for each administration, of which about 15-30 minutes are enterally administered. You don't have to be patient.

  In addition, you may use the liquid food bag 1 when hand-squeezing or pressurizing and administering to a patient.

  Although the example of nasal nutrition administration was shown, as shown in FIG. 7, the liquid food bag 1 may be used for enteral nutrition administration. In this case, first, the patient-side connector 56 of the catheter 54 is connected to a gastrostomy 57 formed on the stomach of the patient 60 by percutaneous endoscopic gastrostomy. The cap 52 of the liquid food bag 1 is opened, and the outflow port 51 is screwed into the bag side connector 53 of the catheter 54 so that it does not fall out at the outflow port step 51c. Next, the hanging hole 30 is passed through the hook 71 of the stand 70 to hang the liquid food bag 1. The liquid food bag 1 is slightly inclined due to its own weight. If necessary, the flow path of the liquid food 40 is adjusted by closing the flow path of the catheter 54 with the clamp 55. Then, the liquid food 40 slowly flows out from the liquid food bag 1 to the catheter 54 and is administered to the stomach of the patient 60 via the patient side connector 56 and the gastrostomy 57. Thereafter, post-processing is performed in the same manner as described above.

  In addition, the liquid food bag 1 does not have a soft bag sheet tearing yarn, and may be unopenable.

  The liquid food bag 1 of the present invention is used in nasal nutrition administration and enteral nutrition administration for administration to a digestive tract such as the stomach from the nasal cavity or gastrostomy to a patient with eating disorders.
